Try the old trick of taking the battery out and leaving it for a while. They can often reset things. Otherwise there is a option to reset everything to factory defaults, so try that. Otherwise, I'm stumped.

K mount to M42 adaptors are readily available. Make sure you get the sort that sits flush inside the throat of the camera as the ones with a flange stop the lens focusing to infinity. Genuine Pentax adaptors are now an insane price. Second hand ones are available on ebay. SRB-Griturn also make good quality adaptors for less than the genuine Pentax ones.

The easiest way to use a Super Tak on a K20D is put the camera in Av mode. Use the Auto-manual slider on the lens to open and close the aperture. Have it on auto (wide open) to focus and then slide it to manual (stopped down) to shoot.

Great review Hefty. You aren't doing my LBA any favours!

Best wishes, Kris.

In the develop module select the "white balance selector" tool found in the white balance panel. Then find something white (or neutral gray) in your image and click on that. Job done.

If you know in advance you are going to be using that lens, take a photo of something white (e.g., a sheet of paper) in the light you will be using and either set the WB manually in camera or use that to work out the white balance setting needed in Lightroom.

I have the remote F but it has a very limited range. Any recommendations on one with a longer range? If I have the camera on self timer I'll have time to pop the remote in my pocket before the camera fires.

Thanks, Kris.

I'll be able to scout the day before but no sooner, although I have been there before and so know more or less where we are planning to be. I'll have my tripod with me so that part is no problem.

I had thought fill-in flash would be the way to go. I'll have to find a willing victim to practice on if we ever get a sunny day!

Thanks John.

As regulars here may have noticed, on the whole "I don't do people" (to misquote a Flanders and Swann song) and I am very much an available light person. I'd like some advice from the collective expertise here for some photos I have to take in mid-June. Here is the scenario...

1) I need to take some photos of a small group of people (4 or 5) in various configurations, some head and shoulders shots and some full length shots.

2) The group will be outside in "The Garden of the Gods", a fantastic park in Colorado with stunning geological formations which will form the backdrop.

3) I have no idea what the weather will be like but there is a good possibility it will be bright and harsh light.

4) Clearly, I will need some form of fill-in light to soften the shadows, either fill-in flash or a reflector.

5) I will be using my K20D (or K10D?) and have various tripods, lenses and flashes available.

6) So far so simple? Here is the major complication: I will have to be in most of the photos!

I'd be interested in any comments on the best way of lighting this sort of group, and any ideas on how best to be in the photo and setting them up!

Best wishes, Kris.

You have to be a bit clearer about what you are saying, it is so abbreviated it is unclear what has happened.

That aside, £1,830.56 for a 135mm manual lens seems a bit excessive!

I do! Archaeologists developed the idea of "preservation by record" which means that a site can be destroyed by a developer provided archaeologists have excavated it and produced an accurate and detailed record of the site. This leads to discussions about the paper the forms are printed on, the type of pen used to make the records, and the film used to take the photos. Kodachrome 64 was the recommended slide film, and BW had to be processed to "archival standards".

Best wishes, Kris.

What does the trigger on a Tamron 70-200mm lens actually do? Some sort of fancy focusing system:
